The correct option is Br, Cl
What are halogens?
Fluorine (F), chlorine (Cl), bromine (Br), iodine (I), astatine (At), and Tennessee are the five or six chemically related elements that make up the halogens group in the periodic table (Ts). Group 17 is the name given to this group in the current IUPAC nomenclature.
The definition of "halogen" is "salt former" (or "salt maker"). Silver bromide, potassium iodide, calcium fluoride, and sodium chloride are just a few of the compounds that are created when halogens combine with metals.
There are other families of halogen oxides that are known to form various anions, including the one shown in the figure attached to the question but which I am unable to reproduce here.
Chlorine, bromine, and iodine frequently combine to create these anions. When the halogen's octet expands, these anions are created. This suggests that the halogen's outermost shell now has more than eight electrons.
Hence, Br and Cl are the correct option
